music TURNER AND CARRIER.

Specification of Letters Patent.

Patented Nov. 22,1921.

Application filed January 31, 1920. Serial No.- 355,306.

' so that the same may be transported or carried from place to place,together with such additional music as it may be desired to play,

and to turn the same successively in the playing, reverse the same orreturn all of the sheets to an initial position so as to accommodate forrepeats or replaying.

A further object of the invention is to provide a device of thecharacter specified which can be just as conveniently moved from onepiano to another as a song book or folder,

7 in addition to being a relatively desirable and perfect form ofcarrier or folio; which can be applied to a Il'lllSlC stand as well asto a piamo, and which includes novel means for actuating a series ofarms independently to turn thepages or sheets as the notes are playedand each sheet is completed to permit said turning arms to be reversedat will and to permit all of them to be turned back after the playing iscompleted, such mechanism being capable of convenient control by a handor foot without inconveniencing the playingaction and including amotoror actuating means of novel construction and simple in design,whereby the device is capable of being economicallyproduced and sold.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combine-j. tion andarrangement of parts and in'the details of construction hereinafterdescribed and claimed, it being understood that within the scope of whatis claimed, changes in the precise embodiment of the invention shown canbe made without departing from the spirit of the invention.

and

Fig. 7 is'a sectional elevation of the device looking toward one side.Referring to the drawings in detail, my improved music turner andcarrier embodies a carrler proper 10 which is in the form of a folio orfolder having the back portions 11 and 12 provided with the intermediateor binding portion 13Vmuch in the same mannor as an ordinary folio orbook. The device is covered with leather, leather imitation or the likeover stiff backings, which backings are provided with cooperatinghandles M for convenience in transporting or carrying the device fromplace to place. A fastening strap l5-is also provided on one backing toengage -its cooperating snap fastener or socket member with a snap orball member 16 carried by the other, although it is to be understoodthat any other suitable fastening means passing over the free edges andconnectingthe backings' may be employed. In this manner, the carrier orfolio may be opened so as to rest upon the ledge of a piano musicsupport or panel in convenient position for use.

Each of the backings is provided with a suitable covering of leather orcloth at the inside as designated at 17 and each is formed with a pocket18 between the inside lining and the outside cover or backings foracconi modating additional music as clearly indi nearly at the top orslightly spaced from the top edge of the folder and suitably secured inposition. This tube rotatably receives spindle 20, the upper end ofwhich. is of circular cross section and provided with a transverse keyor pin 21 above the upper end of the tube or tubular casing. A series ofturning arms 22 horizontally disposed are provided with leafengagingclips 23 ant 1 spindle and arms are exposed, the remain said arms areprovided at their inner ends with sleeves 24ihaving'internal' 'roovesorkey. slots 25 preferably terminating. at spaced points from the upperandlower edges or ends thereofforreceiving the pin or. key 2l during theturning action, while the intermediate recesses 26 accommodate said pinbetween motions." The'upper arm has its sleeve or hub in alinementtherewith and the sleeves therebeneath' are successively offsetdownwardly at diii'erent degrees or lengths as indicated at 27 so thatthe sleeves are accommodated on the projecting upper end of the spindleto turn freely thereon except 7 when engaged by thekey or-pin 21 At itsintermediate portion, the "spindle 20; is provided with a spiral grooveor worm thread 28 the spindle bein enlar ed at this portion if desiredandthe tubular housing '19 having an opening 29 disposed through'itswall axially of a. latch casing 30 projectinggfromthe housing. Alatch or pin 31 is mounted in the casing and has a finger hold 32 bywhich it may be disengaged at its inner end from the groove, it beingunderstoodthatsaid pin opposite its headedend engages the spiral groove28, after passing through-the opening-29. The pin is held in an engagedposition in the manner of a spring pressedibolt or catch and for thispurpose is provided with a-nenlargement33 within the casing, betweenwhich andthe outer end of the casingiso, as to encircle the piI1,. isdisposed an expansible helical, spring 34; so as to hold'the pinnormally in an engaged position by pressure against said enlargement orcollar 33. By this means, the spindle may be caused to elevate as itturns or by withdrawing the pin, the spindle may be allowedto drop,.sothat the key 21 will be disposed in the grooves ofthe lowermost sleeveor hub 24L whereby-the sleeves may be successively turned or swung tothe left to turn the music sheets as the spindle is intermittentlyI'D-1: tated and the means above described causes its elevation andsuccessively brings the key. into engagement with the grooves of the.

insideforming shoulders 51Ifacing in sleevessucces'sively one above theother. 'It will be also understood as the key passes into the recesses,the sleeves will'be released until the next groove is engaged toturn thesuc ceeding arm as desired. When all of the arms'havebeen turned andconsequently the sheets, they may be turned back by means of an uprightarm 35 carried by a said springs from unwinding, the gears ring 36 fromwhich it projects upwardly. the ring having a finger piece 37. by whichit may be turnedin a groove in the housing 19. It willalso be understoodthat the arms may be independently turned or swung backwardly forrepeating or the like.

.As shown particularly in Fig. l of the drawings, the upper portion ofthe housing,

ing portion being covered by the lining 17. The upper portion. of thespindle is of round or circular cross section as before stated, andthelowerportion is of polygonal or square cross section as 'indicatedat 38so as to be connected to the actuating device or motor which includesacasing 39 in which is rotatably mounted V crown wheels mesh with theopposedin wardly' extending teeth of the crownv gears iO avhich aremounted to turn in the casing on stub shafts or p1vots43 which are fixedto thecasi'ng. Connecting the shafts or, p vots 43 and the crown gearsarespiral springs 144: like clock springs, the ends thereofbeing-connected to the pivots'and to the gears res ectivelyslidablyfengaged' beveled pinion or m1tergear/i2-d sposed tosoas tooperate the pinion 42 andthe shaft thereto. V In order-to wind thesprings, the casing is provided with a depending extension ao;

in mesh with peripheralteeth' disposition at diametrically oppositereverse directions.

By pulling the'shaftjoutthrough the mediumof the key, the frontlgear spring maybe wound, and bydisposingrthepin on 57 at intermediate position,

provided with ratchetextensions 50at the to be engaged'by a catch orpawl 52 passing through the casingat one side. and pivotedintermediately of its ends on a vertical pivot 53 in a lateral extension54: formed on or attached to the casing. At 7 v 7 either, gear 40. Wlllbe. free to turn. In orderctopre' are.

L the direction in which the gears turn adapted eitherside of the plvot,the pawl is provided with push buttons 55 and 56 so that the pawl may bereleased from the position shown in Fig. 7 underlying the shoulders ofboth ratchet sleeves or extensions 50, wholly beneath one shoulder sothat the other shoulder will be released in order that the correspondinggear may act under its spring to turn the pinions 42 and the spindle orshaft 20.

It will be seen that the shank portions of the buttons project throughthe lining 17 as well as the key 49 and in the operation of the device,the arms are disposed at the right hand side and engaged with the musicsheets, except that the arm 35 will be disposed at the left. The spindle20 will be in its lowermost position and with the springs properly woundand held from'unwinding, the button 55 is depressed or repressedinwardly to rock the pawl 52 on its pivot 53 whereby the inner end ofthe pawl operating through the slot 57 in the casing at one side, willbe disengaged from the shoulder 51 of the rear gear and into en gagementwith the shoulder of the front gear, thus holding the latter as beforeand releasing the former so as to turn the pinion 12 and the spindle ina clockwise direction or to swing the arms22 successively to the left asreleased to correspondingly turn the sheets. By pressing the button 56,the pawl will be moved in the opposite direction to release the frontgear and permit the other spring to act to return the arms to the righthand side, the rear gear being held against turning by engagement of thepawl beneath the corresponding shoulder 51, a seriesof which areprovided corresponding to the spaced series of teeth on the gears 48. Inthis manner the arms may be independently returned for repeating, and itwill also be seen that when the pinion 42 is disposed between smooth ormutilated portions of the gears or crown wheels .48, the spindle 20 maybe freely turned by the upright arm 35 to return all of the arms andsheets to closed positions. The key 4:9 and the buttons 55 and 56 areconveniently located so as to be readily manipulated by the player andit will be seen that the buttons can be operated without interference tothe playing. 6

In Fig. tof the drawings the device is shown applied to a music stand58, preferably of the foldable type having the legs 59 and the rest 60to the ledge of which is secured an arm 61 having pivoted thereto aplurality of hell crank levers 62, one for each button and connected byrods 63 to foot pedals 6e pivoted to the legs so that the buttons may bemanipulated by the feet. Thus itwill be seen that I have provided asimple and relatively inexpensive device for inclosing music folders orbooks and for supporting the same in position to be turned and turningthem as desired, whether applied to a piano or music stand adapted foruse in playing string instruments, although it is to be understood thatthe device may be applied equally as well for turning sheets or pagesother than music sheets, as for instance, for exhibition purposes or thelike.
